The upgrade contract is that a customer installs each stack major version in order, derived from the version numbers alone so nothing has to publish a catalog or maintain a floor per release. What that rule needs in exchange is that a major boundary is actually cut whenever a candidate contains something a customer cannot safely skip past. That is not decidable by eye. A stack-pin diff is a list of chart versions moving, and nothing in "1.5.3 -> 2.0.0" says a migration landed. In a monorepo the evidence is computable instead, which also means it cannot be forgotten the way a declaration written in a pull request months earlier can. Additive migrations never qualify: golang-migrate applies the ordered set per keyspace, so a cluster many versions behind still arrives at the right schema. Destructive migrations and deleted migration files do, because a drop is unrecoverable without a restore and a deleted migration is how a compatibility bridge stops shipping. Comments are stripped before classifying. nvcf_api/03_init_tables.up.sql documents a "high-churn write/delete workload" above a CREATE TABLE, and a classifier reading raw text calls that destructive. Run over the current corpus the classifier finds exactly the four real drops and leaves the other 38 files additive. The baseline is the stack's last release tag rather than the pinned migrations image, because the stack does not pin that image yet (#1976).

…heck Comment stripping only handled `--`, so a DROP inside a block comment or a CQL string literal read as executable. Both fail in the over-strict direction: they would have blocked a legitimate non-major release over SQL the database never runs. stripComments now scans line comments, block comments and quoted strings, emitting a space for each so removing one cannot weld two tokens into a third. The doubled-quote escape is handled, without which the scanner stays inside a string and misses every statement after it. A rename recorded only the new path, as Modified. Renaming a migration away therefore produced no Deleted change and Decide would permit a non-major release even though the old migration no longer ships. Renames now emit a delete for the old path and a change for the new one. Copies do not, because a copy leaves its source in place. The early return for a stack with no migration paths printed text before the JSON branch, so --json emitted non-JSON for the compute-plane and observability stacks. Both paths now go through one emit(), and the report carries `checked` so a consumer can tell "no schema shipped" from "no changes". None of the three is reachable from the current corpus: no migration uses a block comment, a string literal, or a rename. They were all live paths into a wrong answer.

The customer-side gate does not exist yet, so the rule it will enforce has nowhere to live and nothing holding it still. This is that rule as executable cases, so the hook in #1977 is built against a specification rather than the specification being inferred from whatever the hook ends up doing. The rule is that a customer installs each major version in order, derived from the version numbers alone. The case that needs care is a cluster with no recorded version: it predates the receipt writer, and a 0.x install and a 1.0.0 install are indistinguishable from there. Refusing both outright makes the gate unshippable, since no existing customer could ever adopt it, and allowing both makes it useless, since a 1.x to 3.x jump also arrives without a record. Backporting the writer to the 1.0 line resolves it: absence becomes a refusal that names a version the customer can actually install. Every refusal carries the next hop. A refusal that only says no is a dead end, which is what made fail-closed unusable before the backport. This is version arithmetic only. Whether a required data migration finished is a separate axis, tracked per chart, because a version number cannot express it.

Handle double-quoted identifiers in stripComments.
Classify processes .sql files as CQL migrations. CQL permits arbitrary characters inside double-quoted identifiers and uses "" as the escape. The scanner currently handles only single-quoted strings. An apostrophe inside a valid identifier can consume the rest of the file, so a later DROP, TRUNCATE, or DELETE is missed. A /* sequence can do the same when no */ occurs before the later statement. A -- sequence can hide a later statement when the statement remains on the same line. It does not hide every later line. OpenBao migrations are shell scripts and do not reach this function.
Skip double-quoted identifiers with doubled-quote escaping. Add focused tests for these three characters followed by a destructive statement.

Stacked on #1983 — it adds to the same module, so the diff shows both until that merges. Review this one for the last commit.
Gives #1977 a specification to build against, rather than inferring the contract from whatever the hook ends up doing. No production behaviour changes;
CanUpgradeis not wired into the CLI yet.The rule
A customer installs each major version in order, derived from the version numbers alone — no catalog, no per-release floor metadata.
The case that needs care is a cluster with no recorded version. It predates the receipt writer, and from there a 0.x install and a 1.0.0 install are indistinguishable. Refusing both outright makes the gate unshippable, because no existing customer could adopt it. Allowing both makes it useless, because a 1.x → 3.x jump also arrives without a record. Backporting the writer to the 1.0 line (#2012) resolves it: absence becomes a refusal that names a version the customer can actually install.
Why every refusal names the next hop
A refusal that only says no is a dead end. That is precisely what made fail-closed unusable before the backport.
Scope
Version arithmetic only. Whether a required data migration has finished is a separate axis, tracked per chart (#1979), because a version number cannot express it.
